This study investigates electrical energy conservation opportunities at SABIC Research and Technology Centre, Bangalore, aligning with SABIC’s global sustainability goal of a 15% reduction in energy consumption. The facility, with an average monthly consumption of 6.5 lakh kWh, aims to achieve a 10% reduction by 2026. A two-phase methodology—Energy Assessment and Optimization Planning—was employed. The assessment involved detailed analysis of HVAC systems, air compressors, chillers, cooling towers, lighting, and process equipment. Optimization strategies included retrofitting Air Handling Units (AHUs) with Electronically Commutated (EC) fans, implementing IoT-based Lab Environmental Monitoring Systems, and deploying Variable Speed Drives (VSDs) for compressors. Data-driven analysis revealed potential savings of over 1.2 million kWh annually from AHU upgrades alone, with a return on investment (ROI) of 1.66 years. Additional interventions in transformer load management, chiller sequencing, and power factor correction further enhanced efficiency. The study concludes with a roadmap for implementation, monitoring, and policy integration. Results demonstrate significant operational cost savings, improved equipment lifespan, and enhanced environmental performance. This case study serves as a replicable model for industrial energy optimization in tropical climates [7, 17].
